Bullet Proof Mindset Course - The Most Influential Single Police Trainer in America

Lieutenant Colonel David Grossman is the most influential single police trainer in the United States. More than 100 police departments in the US and 1000s of officers, perhaps tens of thousands have taken Grossman's courses over more than 20 years. His teachings have made their way into mainstream Hollywood blockbusters. He has been nominated for a Pulitzer Prize but I don't know that he did.
